Pin to `hilevel_serman` dev branch for `tractor`

By passing down the `tractor.hilevel.ServiceMngr.debug_mode: bool`
(normally proxied in from the `--pdb` CLI flag) to `spawn_brokerd()` and
adjusting the `_setup_persistent_brokerd()` endpoint to do the
`tractor.devx.maybe_init_greenback()` if needed.

Also in the `broker_init()` factory merge all `tractor` related `kwargs`
(i.e. `start_actor_kwargs | datad_kwargs | spawn_kws`) into the 2nd
element returned as to be passed to `ActorNursery.start_actor()`. Start
re-naming some internal vars/fields as `datad` as well.
